Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:

- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Why does my mac air reject new wifi password when all other devices work fine

My mac air rejects our new wifi password, but all other devices are working fine including this ancient mac. The mac air is OSX 10.8.5

Power Cycle
Power off the router. Unplug it from the wall. Wait a while.
Plug it back to the wall. Power the router on. Wait until all the lights are lit properly. It will take a while.
Restart the computer.

Wifi connection unreliable only on my HP 23-h020a, all other devices work fine

We have just bought two brand new HP devices but are having major problems with the pavilion 23-020a. Basically the wifi connection is rubbish! All other devices in the house work fine and the PC itself is only a couple of meters from the modem and showing full connectivity. However we cannot reliably get internet connection when using wifi. Sometimes it's fine for a couple of minutes, some pages load, some don't, if my kids are in the middle if doing their home work when it comes to them moving on to the next page to do their online test, the page won't load and all their work is lost. This is totally unacceptable! If we connect using the Ethernet cable it's fine but to do that we have to have two meters of cable running across our sitting room. I need this resolved! We have tried all available wifi channels and nothing has helped. I hope someone here can! Thanks

TS1398 My I pad is 14 motnhs old and previously worked fine on my home wireless network. All other devices work fine, but now, my I pads capability (range) is greatly reduced. Is there anything to check on the ipad for WIFI antenna strength?

My Ipad is 14 months old and previoulsy worked fine on my home wi fi network. Recently the range is diminished but all other devices (ipods, ps) are working just fine. Is there anything to check functionality of the wi fi antenna? Has anyone has similar problems? Unfortunately, the warranty expired 2 months ago.

I am trying to add my Zimbra email to apple mail in Lion. No matter what I try i am either not able to connect to the server. I have the correct username, password, server address, act. But still no luck..Anyone got any suggestions? Im stumped

Have a Zimbra server at work for my work emails which I also use to recieve my emails on my Iphone. I have been trying to set up for email for our Zimbra server at work on my new Mac Mini's mail. I have server address, User Name, Password, and have tried all the various ways to set it up. On my Iphone 4 it is set up in the mail config as an exchange. I tried to copy the settings my iphone uses and imput them into the mail setup. Every time I have tried POP, IMAP, Exchange I get a message that it cannot connect to the server and I should check my connection to the internet. I kinda had a similar problem setting it up on my Iphone initially. I am starting to think that Apple is lacking when it comes to its native mail app. It has no problem registering my google email but for some unknown reason it wont take my work email through exchange. Really Scratching my head, any ideas?? Thanks again for taking the time to read.

I have yet to find an email server that does not work with Mail.app. Your solution will be to configure its ports and send/receive protocol according to the email server's requirements.
Try the Zimbra support forums. I found this excerpt from a relevant post:
http://www.zimbra.com/forums/users/46221-mac-mail-app-dont-work-outside-company. html
in which the following ports were suggested
ports 25, 465, and/or 487 to send mail.
port 143/993 to retrieve mail over IMAP

New internet provider, Apple devices can't download updates/apps but all other devices work fine! help

Hi there
I have changed to a new internet provider, and they configured my router (which was working fine previously with my Apple devices)
It is a D-Link router, and it is connected to the internet via PPPOE. (previous provider did not have this PPPOE configuration)
The technician did the configuration and the Wifi works fine for all my devices including laptops, and friends who use Android.
My Iphone, Ipad, and my friends' ones are the only things that seem not to work correctly.
They can find the network on the router. It then connects for a short time, then either after a few mins of browsing on Safari, or any attempt to download an App or update an App, it fails.
To summarise - All non-apple devices function fine and connect to router. Apple Iphones and Ipads find and connect to Wifi, but the internet works temporarily on browser, and any App update or download will fail. (Wi-fi remains connected)
I am hoping it is a simple router configuration issue and the installation technician missed something. Has anyone ever come across this?
what I have tried - Rebooting router, restarting Ipad, resetting network settings and other things, but I am almost certain it is a router configuration thing.
Just hope someone can help, because I have called my internet provider and if they will charge for a call-out if they find it is not ''their fault'.
Really really appreciate any answers to this one.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.

4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are drooping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

Try forgetting the Wi-Fi network and then joining it again, just tap Settings > Wi-Fi > the arrow next to your network > Forget this Network, then join the network again.
If that doesn't do it, take a look at this Apple doc -> iOS: Troubleshooting Wi-Fi networks and connections

I Cannot get FaceTime to work on my mini. It gives me a network error. But all my other devices work fine.

Quite a few people have posted about having issues with Facetime and iMessages over the past few weeks. The update to iOS 8.1.3 was supposed to address those issues and you could try updating your iPad. But the fix didn't work for everybody.
IF you are getting the message about checking your network connection, start with these very basic troubleshooting steps.
Check Settings>General>Date & Time>Set Automatically>On. Make sure that the time zone setting is also set correctly.
If that didn't solve the problem, restart your iPad and try again. If that fails, reset your iPad and try again.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
